单选题Read the following text. Choose the best word(s) for each numbered blank and
mark A, B, C or D on. Most worthwhile careers
require some kind of specialized training. Ideally, therefore, the choice of an
{{U}} {{U}} 1 {{/U}} {{/U}}should be made even before the choice
of a curriculum in high school. Actually, {{U}} {{U}} 2 {{/U}}
{{/U}}, most people make several job choices during their working lives, {{U}}
{{U}} 3 {{/U}} {{/U}}because of economic and industrial changes and
partly to improve {{U}} {{U}} 4 {{/U}} {{/U}}positions. The "one
perfect job" does not exist. Young people should {{U}} {{U}} 5
{{/U}} {{/U}}enter into a broad flexible training program that will {{U}}
{{U}} 6 {{/U}} {{/U}}them for a field of work rather than for a
single {{U}} {{U}} 7 {{/U}} {{/U}}.
Unfortunately many young people have to make career plans {{U}} {{U}}
8 {{/U}} {{/U}}benefit of help from a competent vocational counselor or
psychologist. Knowing {{U}} {{U}} 9 {{/U}} {{/U}}about the
occupational world, or themselves for that matter, then choose their lifework on
a hit-or-miss {{U}} {{U}} 10 {{/U}} {{/U}}. Some drift from job
to job. Others {{U}} {{U}} 11 {{/U}} {{/U}}to work in which they
are unhappy or for which they are not fitted. One common
mistake is choosing an occupation for {{U}} {{U}} 12 {{/U}}
{{/U}}real or imagined prestige. Too many high-school students—or their parents
for them—choose the professional field, {{U}} {{U}} 13 {{/U}}
{{/U}}both the relatively small proportion of workers in the professions and the
extremely high educational and personal {{U}} {{U}} 14 {{/U}}
{{/U}}. The imagined or real prestige of a profession or a "white-collar" job is
{{U}} {{U}} 15 {{/U}} {{/U}}. good reason for choosing it as
lifework. {{U}} {{U}} 16 {{/U}} {{/U}}, these occupations are
not always well paid. Since a large proportion of jobs are in mechanical and
manual work, the {{U}} {{U}} 17 {{/U}} {{/U}}of young people
should give serious {{U}} {{U}} 18 {{/U}} {{/U}}to these
fields. Before making an occupational choice, a person should
have a general idea of what he wants {{U}} {{U}} 19 {{/U}}
{{/U}}life and how hard he is willing to work to get it. Some people desire social
prestige, others intellectual satisfaction. Some want security, others are
willing to take {{U}} {{U}} 20 {{/U}} {{/U}}for financial gain.
Each occupational choice has its demands as well as its rewards.
